I have the same problem with my 3 year old. She just recently had one time that she could not find me and just went by herself. I noticed and praised her lavishly by picking her up, spinning her around, giving high fives, doing a happy dance. She was so excited by all the attention that she has slowly started going by herself on occasion. Every single time she goes by herself I act like a crazy mamma giving her all kinds of attention. I'm hoping this will work since I know she can go on her own but just wants the attention from mommy. Going well so far.
